CONNECTING STRUCTURE OF BRANCH CONNECTOR IN FUEL PRESSURE ACCUMULATING VESSEL

摘要

PROBLEM TO BE SOLVED: To provide a connecting structure of a branch connector in a fuel pressure accumulating vessel for improving internal pressure fatigue strength by reducing stress concentration generated in an inside end peripheral edge part of a branch pipe and a joint metal fitting as the branch connector.

SOLUTION: This connecting structure of the branch pipe is connected and constituted by projecting a tip part of the branch connector up to the passage inside or the vessel inside from a vessel inner peripheral wall surface by deeply inserting the branch connector into a through-hole by arranging a flat part in the inner peripheral wall surface part of at least a shaft directional position of the through-hole arranged in a peripheral wall part of the pressure accumulating vessel, and is characterized by setting a width or a diameter of the flat part larger than a maximum width or a maximum diameter of at least a brazing fillet.
